Game Programming Using Qt: Beginner's Guide

By: Lorenz Haas, Witold Wysota, Witold Wysota, Lorenz Haas

Overview of this book

Qt is the leading cross-platform toolkit for all significant desktop, mobile, and embedded platforms and is becoming more popular by the day, especially on mobile and embedded devices. Despite its simplicity, it's a powerful tool that perfectly fits game developers’ needs. Using Qt and Qt Quick, it is easy to build fun games or shiny user interfaces. You only need to create your game once and deploy it on all major platforms like iOS, Android, and WinRT without changing a single source file. The book begins with a brief introduction to creating an application and preparing a working environment for both desktop and mobile platforms. It then dives deeper into the basics of creating graphical interfaces and Qt core concepts of data processing and display before you try creating a game. As you progress through the chapters, you’ll learn to enrich your games by implementing network connectivity and employing scripting. We then delve into Qt Quick, OpenGL, and various other tools to add game logic, design animation, add game physics, and build astonishing UI for the games. Towards the final chapters, you’ll learn to exploit mobile device features such as accelerators and sensors to build engaging user experiences. If you are planning to learn about Qt and its associated toolsets to build apps and games, this book is a must have.

In the first part of this chapter, you familiarized yourself with QNetworkAccessManager. This class is at the heart of your code whenever you want to download or upload files to the Internet. After having gone through the different signals that you can use to fetch errors, to get notified about new data or to show the progress, you should now know everything you need on that topic.

The example about the Distance Matrix API depended your knowledge of QNetworkAccessManager, and it shows you a real-life application case for it. Dealing with JSON as the server's reply format was a recapitulation of Chapter 4, Qt Core Essentials, but was highly needed since Facebook or Twitter only use JSON to format their network replies.

In the last section, you learned how to set up your own TCP server and clients. This enables you to connect different instances of a game to provide the multiplayer functionality. Alternatively, you were taught how to use UDP.
